The effects of biasing information on behavioral observations and rating scales

The effects of biasing information on behavioral observations and rating scales were studied. Fortyone undergraduate students trained in making reliable behavioral observations were given differential expectations concerning the activity level of a target child. They then viewed videotape recordings of that child and tallied frequency counts of six behavioral categories simultaneously. In addition, subjects completed postexperimental rating scales composed of specific, identifiable behaviors in regard to the target child. Results indicated that, for the most part, neither the behavioral observations nor the rating scales were significantly affected by the biasing information. It is suggested that rating scales constructed of items as discrete and readily identifiable as those of behavioral observation measures may prove resistant to biasing effects.This study is based in part on a thesis submitted by the second author to Case Western Reserve University in partial fulfillment of the requirements for the master of arts degree in psychology. The authors express their appreciation to the Claremont Unified School District, Claremont, California, for their assistance in the production of the videotape and to the Instructional Support Center at Case Western Reserve University for their co-operation in providing research space. Special thanks are given to Thomas Hyde for his advice and assistance throughout the study.

Differential reinforcement of lever-press durations: Effects of deprivation level and reward magnitude

Three experiments investigated the performance of rats on a task involving differential reinforcement of lever-press durations. Experiment 1, which employed a discrete-trials procedure, manipulated deprivation level between subjects and reward magnitude within subjects. The minimum lever-press duration which would result in reward was varied from .4 to 6.4 sec. It was found that low deprivation resulted in longer mean durations and less response variability at the higher criterial values than did high deprivation. The magnitude of reward was not found to affect performance. Experiment 2 manipulated reward magnitude between subjects while holding deprivation level constant, and used the same general procedures as in Experiment 1. Small reward resulted in longer mean lever-press durations and less variability in responding than did large reward at the higher criterial values. The intertrial intervals were omitted in Experiment 3 in which deprivation level was varied between subjects and reinforcement was delivered only for response durations extending between 6.0 and 7.6 sec. Low deprivation resulted in longer mean lever-press durations and less response variability than did high deprivation, but the probability of a rewarded press duration did not differ between groups. The results overall are consistent with the hypothesis that low deprivation and small reward magnitude lead to weaker goal-approach responses and, hence, to less competition with lever holding. The deprivation and reward magnitude manipulations did not appear to influence lever holding performance by affecting the ability of animals to form temporal discriminations.     

The black male urban barbershop as a sex-role socialization setting

Two hundred-eighty participants-as-observer hours and eight hours of informal interviewers with “informants” during a two-month period in summer 1983 were data sources in an analysis of a Black male urban barbershop in a midwestern city. The study focused on the barbershop as a sex-role socialization setting in which adult Black males actively negotiate masculinity while Black male youth passively negotiate masculinity and in all likelihood are socialized to become active negotiators. Content analyses of taped barbershop sessions and the researcher's written reports of the session revealed that the barbershop studied perpetuates sex-role stereotypes, encourages sexist attitudes toward women, and, in general, is a sex-role socialization setting that promotes sex-role inequality.     

Nostalgia for America's past can buffer collective guilt

This research examined when, and for whom, American collective nostalgia can relieve feelings of collective guilt. In the Pilot Study, path analyses revealed that national glorification is associated with collective nostalgia, and collective nostalgia is associated with lower collective guilt. Our experimental studies test the role of these variables in determining responses to the elevated salience of past ingroup harm doing. Collective nostalgia was associated with lower collective guilt especially after reminders of America's harm doing in Study 1 . In Study 2 we predicted and showed that reminders of American harm doing would evoke spontaneous collective nostalgia for participants high in national glorification. The remaining studies tested the hypothesis that collective nostalgia serves to buffer collective guilt. Collective guilt was lower after reminders of past harm doing for participants who engaged in collective nostalgia ( Study 3 ), and this was especially pronounced for participants high in national glorification ( Study 4 ).     

Family Support and Mental Health in Pregnant Women Experiencing Interpersonal Partner Violence: An Analysis of Ethnic Differences

This study investigated the relationship between family support and mental health in a community sample of pregnant women experiencing interpersonal partner violence (IPV). This study also examined how family support may differentially affect mental health in Black and White women experiencing IPV. A total of 110 participants (32 Black and 78 White) were obtained from the first time period of a longitudinal study examining the effects of domestic violence on women. The model was supported (χ² = 142.55; df = 72, p > .001, RMSEA = .07). Black women had better mental health than White women. However, ethnicity was not a significant predictor of family support. Implications from this study highlight the need for further research on the role of family support in the lives of physically abused women as well as the need to incorporate cross cultural perspectives when examining this issue.     

From dissonant dominance to synchronic sanctity: Relational extraction as counter-resonance to extractivism

There is a growing tendency within various disciplines of the humanities to conflate the terms extraction and extractivism. While the first word has many everyday uses—tooth extraction, vanilla “extract”—the latter term was specifically coined to identify a malevolent imaginary that indemnifies the removal of so-called “resources,” especially when that displacement involves layers of violence and/or looks solely to satisfy a particular economic aim. Given these disparate denotations, the unqualified use of “extraction” synonymously with “extractivism” introduces unnecessary ambiguity, inviting divergent arguments that ultimately diminish an otherwise worthy discussion and losing sight of the grave issues that underlie the conversation's original intent. As such, this essay investigates the biblical origins of this false equivalency and suggests how this usage might be disentangled to properly recenter the malevolence its users are attempting to describe.
